Subjective speech evaluation is important in maxillofacial rehabilitation. In previous research, the automatic speech intelligibility test system using monosyllables was developed using a computerized speech recognition technique, and it was suggested that the system may effectively be used in evaluated maxillectomy patients' speech. However the system showed some disadvantages such as the low sensitiveness for the mild speech disorders. In this study, the system was remodeled employing sentences as test stimuli to overcome the shortcomings. The new system was used to evaluate speech of normal adults and maxillectomy patients.
The speech of 10 normal adults and 13 maxillectomy patients was evaluated using the automatic conversation intelligibility test system that employed sentences as test stimuli. Normal subjects repeated the test for three times on different days. The patients' utterances were examined in two conditions: with and without prostheses. The results from patients with and without prostheses were compared to each other, and also compared with their corresponding conversation intelligibility obtained using a perceptual method.
In normal subjects, there was no significant difference in their scores using the automatic conversation intelligibility test on three different days. The result of the automatic test was significantly improved in patients by wearing prostheses. There were significant correlations between the result of the automatic test and the corresponding conversation intelligibility both in patients with prostheses and without prostheses.
It was indicated that the automatic conversation intelligibility test system using sentences as stimuli would be effectively used in evaluating maxillectomy patients' speech.
主观言语评估在颌面修复中很重要。在之前的研究中，使用计算机语音识别技术开发了一种使用单音节的自动言语清晰度测试系统，该系统可有效用于评估颌切除术患者的言语。然而，该系统存在一些缺点，例如对轻度言语障碍的敏感性较低。在这项研究中，通过采用句子作为测试刺激来对该系统进行改造，以克服其缺点。该新系统用于评估正常成年人和颌切除术患者的言语。
使用自动对话清晰度测试系统评估 10 名正常成年人和 13 名颌切除术患者的言语，该系统采用句子作为测试刺激。正常受试者在不同的三天重复进行了三次测试。检查了患者在有和没有义齿的两种情况下的发音。将有和没有义齿的患者的结果相互进行比较，并与他们使用感知方法获得的相应对话清晰度进行比较。
在正常受试者中，在三天中使用自动对话清晰度测试的分数没有显著差异。佩戴义齿后，患者的自动测试结果得到显著改善。在有和没有义齿的患者中，自动测试结果与相应的对话清晰度之间存在显著相关性。
结果表明，使用句子作为刺激的自动对话清晰度测试系统可有效用于评估颌切除术患者的言语。
